Homemade clamps and clamps. Do-it-yourself clamp - how to make a quick-clamping device from metal and wood. Clamp universal for any angle

The clamp is auxiliary tool, which is used to fix the boards when they are connected in a given position. Also, the clamp is suitable for holding boards during their sawing, for wiring a hacksaw blade, connecting various elements. Parts that require machining can be nested in the tool. Then, using a movable element, they are clamped with sponges and get to work. To securely hold parts in position, it is recommended to use two or more clamps.

Home-made staples are often made of metals or wood, and in terms of their characteristics they are not much inferior to purchased, factory-assembled ones. Since the design of the clamping device is simple, it will not be difficult to understand the principle of its operation in order to make it yourself.

Making a screw metal clamp

Before starting work, you will need to prepare necessary materials. For the basis of the structure, a steel sheet one centimeter thick is suitable, any even trimming of the same thickness. The length of the workpiece is arbitrary, but they try to choose it taking into account the working distance of the clamp.

Main manufacturing materials:

• steel sheet;
• long bolts;
• nuts.

A drawing is being made. On the material of the workpiece, the future body of the tool is marked, which in appearance resembles the letter "C". Instead of steel sheet you can use a piece of profiled pipe, bent in the form of the letter "C". There are no special requirements for the thickness of the workpiece, but the design must be reliable. The choice of length is made taking into account the dimensions working area, workpieces.

After marking, the part is cut out of metal. At home blanks small sizes can be cut with a grinder. But in the manufacture of clamps of large dimensions, it is recommended to use a gas cutter, an acetylene torch. The next stage is processing, grinding the workpiece. All sharp edges, sagging, formed when working with gas welding equipment, are knocked off with a file, and the surface is polished with sandpaper. This must be done so that when clamping the workpiece, you do not cut yourself on sharp edges.

Having prepared long bolts M 8, M 10, proceed to fasten the moving element. Why, on one side of the workpiece, nuts are welded under the selected bolts. In the absence of bolts, you can pick up hexagons, steel rods of the desired length with pre-cut threads.

At the inner working end of the screw, a flat, even part is welded, on which the function of the sponges is assigned. On the reverse side of the screw, a lever made of stud scraps is attached by welding. Its presence will speed up the process of clamping workpieces , further reducing the amount of effort applied. This completes the assembly of the clamp with your own hands.

Angle clamp device

When making a corner tool for furniture assembly, it is important to accurately maintain a right angle of 90 °. Main available materials are corners with steel strips. For work you will need:

• 40 mm steel corner 3-4 mm thick;
• steel plates 40-50 mm;
• threaded studs;
• bars for collars;
• nuts;
• welding machine;
• electric drill, taps.

Angle clamp is the most difficult to manufacture, but when carrying out certain types of work, you cannot do without it. On the initial stage corners are welded to the steel plates at a right angle, and nuts are welded to each of the corners, which will serve to create a worm structure. Another option is to drill a hole in the corner and cut into it with a tap internal thread. The width of the working gap is selected taking into account the size of potential workpieces, but too much stroke of the clamping knob reduces the strength of their fixation.

For processing workpieces of different sizes, it is recommended to prepare several clamps!

The stud is screwed into the welded nut. At its end is going to focus from metal washers different diameter, which should scroll freely when the pin is rotated. With reverse side a crank drill a hole for a metal rod. Used as a lever, it will transmit more force, so it will be more reliable to hold workpieces.

Wooden clamp - we will make from the remnants of the boards

The most popular is a wooden quick-clamp clamp, but a tool of a similar design can also be made of metal. Despite the simplicity of the design, it is very convenient when performing various tasks.

The presence of two identical clamps expands the scope of their application!

For assembly, you will need to prepare the following materials:

• pieces of boards;
• studs with pre-cut threads;
• nuts and lambs corresponding to the thread of the studs;
• slats.

First, two threaded studs of the same diameter are prepared. They must be 200 mm long. The nuts are matched to the stud threads. Two slats are being prepared, preferably from wood hard rock. The best choice there will be oak, beech, birch, ash. Reiki are adjusted to the same size. To do this, the excess length is sawn off, and the cut is subjected to grinding. After that, two holes are drilled in each of the rails with a small tolerance. Moreover, the location of the holes on each of the blanks should ideally match, and their diameter should correspond to the diameter of the studs.

Strips of plywood can be glued onto the surface of the rails. They are customized to size. wooden blanks, drill holes. The studs are inserted into the holes obtained and securely fixed with nuts on one of the rails on both sides. Washers are placed under the nuts to prevent material from being squeezed. This bar will always be fixed, but the other will be able to move freely along the guides in the form of studs.

Another bar is installed. To do this, after passing it through the studs, they put it in place. Clamping is carried out using conventional nuts and an open-end wrench, but for convenience and increased productivity, it is necessary to install wing nuts. They check the course of the clamp, if it is difficult or additional fitting of parts is required, other defects are found, then they are eliminated. The work on assembling the clamping device from wood can be considered completed, it remains to test it in action.

Properly assembled clamping devices allow you to securely fasten wooden details during carpentry work. The designs of these types of fasteners are popular and are so simple that they can be made independently from improvised materials with the involvement of a minimum number of tools.

Anyone who has had to make something with their own hands in the direction of improving their own home, there is no need to talk about the importance different kind clamps and clips. Without their presence, it is impossible to imagine both carpentry and metalwork. To qualitatively process any part, you need a clamp. With your own hands, it is quite possible to make it at home with the help of the most elementary tools.

Types and types of clamps

Mechanical clamping devices differ both in purpose and in the material from which they are made. The main raw materials are wooden beam.

Sometimes clamps are assembled with a rather complex spatial configuration: they provide both horizontal and vertical compression of the workpiece being processed. For assembly when constant monitoring is required right angle, the angular clamp is very convenient. It is quite possible to make it with your own hands, but it is better to practice on less complex structures.

Clamps also differ in the type of elements that create mechanical compression. The most common are clamps based on a screw mechanism. But anything that can provide the necessary compressive force can be suitable for the design. Up to cut from old car cameras.

Why not just buy them?

In any tool store, clamps are presented in a more or less wide range. And any master has a sufficient number of them in his arsenal. What usually stops a craftsman from buying another one? First, price - quality tool cannot be cheap by definition. Secondly, it is not always possible to find what you need. Do-it-yourself clamp made for execution specific task, provides the process of assembling the product on an individual basis. With the help of a universal clamp from a tool store, this can not always be achieved.

Disadvantages of a standard tool

On the construction market, you can find a lot of clamps that look like real ones and are expensive, but they only work for a very short time. They are usually made in China. They will have to be thrown away after the money that was paid for them. Most often it fails, it is made of a cheap low-quality alloy. If there is no desire to throw money away, then you should think about how to make a clamp with your own hands. This will not only result in another useful thing in the tool arsenal of the master, but also an increased level of skill and self-respect.

Do-it-yourself clamp: what is needed for its manufacture

First of all, you need to get quality timber from hardwood or a piece of metal rolled profile (preferably channel section) - this is the base on which the stop and the screw mechanism should be mounted. The most important element clamps is exactly it. A bolt with a large thread profile nut is best suited. To assemble the structure into a single whole, you will need a drill with nozzles and standard bolted fasteners. Making clamps with your own hands does not require outstanding qualifications, but you should still have elementary carpentry and locksmith skills.

Making a clamp

The most important advantage of a homemade clamp is its narrow focus on providing a specific technological operation. That is why it is necessary to carefully measure everything and sketch out a schematic drawing of the future product. A self-made clamp can and should last a very long time, but this will only happen if it is correctly designed and correctly assembled.

An emphasis and a screw mechanism must be mounted on the supporting bed bar. The free play of the screw provides sufficient compressive force. The fastening of the stop and the screw with the nut should prevent them from being pulled out of the fixed position when the technological force is applied. An important point is the presence of a flywheel mounted on the head of the process screw. If it is not foreseen and not performed, then the clamp will have to be compressed with the help of which is neither productive nor functional.

In order to possible application clamps as much as possible more operations, the emphasis on it is usually performed in the form of a removable block, which can be placed in several fixed positions. For the assembly of large wooden planes, it makes sense to design a more complex clamp in the form of a system of two or more screws mounted on the same bed base. The efforts invested in the manufacture of a technological tool always give the proper return when using it.

Reading time ≈ 5 minutes

A clamp is a tool that resembles a hand vise, which is used to securely fix or glue two elements together. For example, in carpentry it is used to connect two planes during drying adhesive solution. However, this tool is not always at hand, so you can independently resort to the manufacture of a quick-clamping structure. To properly make a clamp with your own hands from metal, you need to follow step-by-step instructions with photo and video master classes.

Design features

The clamp can quickly fail, so it's important to know how to make homemade tool. Components of this metal structure are the lever part, the frame, the jaws of the clamp and the moving part.

What are the advantages of clamping tools:

The clamp can also be made from wood, however metal structure more practical and reliable. Its manufacture does not require special knowledge and skills, you only need the use of welding equipment, a hacksaw and a burner. The whole process with step by step instructions shown in the video.

Models of clamping tools are divided into the following classes according to the operation of mechanisms and structural features:

Manufacturing technology

A do-it-yourself metal clamp is much more reliable and practical wooden structure. For the manufacture of homemade units would need welding equipment and locksmith units.

Tools for making clamps of any type

1 option

Following the instructions, you can make a homemade clamp from metal fittings.

Option 2

To do it yourself angle tool for clamping, we need the following materials: steel trimmings from the corner 40 * 40, 50 * 50 and 30 * 50 to 200 mm, 2 F-shaped clamps and a strip of 10 * 50 to 250 mm long.

Let's get started:

Purchase clamps at construction stores hard enough. Everyone wants to get rid of extra costs, if there alternative options. You may need several such tools at once, this is especially true when assembling, manufacturing or repairing furniture. Homemade clamps will replace your manual vise, as it is possible to choose the model, type and size of the tool. Following the instructions in the photo and video, you can quickly figure out the manufacturing mechanism and quickly make a manual clamp from improvised materials.

A clamp is a clamping fixture that is used in working with wood and metal, paper and leather. In carpentry workshops, with the help of clamps, parts, boards and shields are glued together, with welding work ah clamp tight parts metal products. In office work, they are used when filing documents for archiving, and in auto repair shops they clamp parts of the mechanism when repair work. The shoemaker with its help glues the soles better.

The clamp is desired part and at home. They can be used to attach a pencil sharpener to a desk or table lamp to bedside table. Even when replacing the battery in good expensive watches you will need the help of a clamp to tightly close the back cover. After all, with high-quality tightness, it closes very tightly.

You can buy a ready-made clamp in the store, but usually several are required at once in production. different products, but they are quite expensive, so most craftsmen begin to think about making a clamp with their own hands.

Types of clamps

Required for work different types such clamping devices. They are made of metal or durable wood. They happen different shapes: F and G-shaped, tape, edge, pipe, quick-clamp, screw, angle or mounting. But no matter how the clamps differ in their structure and appearance, the goal of all devices is the same: to firmly fix the products for further processing or connecting parts to each other.

Angle clamp made of metal

Having made such a design on your own, you can firmly connect not only wooden, but also metal parts to each other. Use these clamps for welding.

To work, you need a steel corner having a thickness of 4 mm and a size of 40 mm, plates of 50 mm, threaded studs, nuts, washers and rods, a welding machine, a drill.

At an angle of 90 degrees, you need to weld the plates to the corners. From each side, also attach by welding a worm structure, which is a small piece of a corner with a welded stop nut, into which a knob with a hole for a metal lever is screwed on top. On the opposite side, a thrust mechanism is assembled, consisting of two washers. The emphasis freely scrolls on a hairpin.

Such an angle clamp is a reliable fastening of parts at a right angle, which can be used not only for welding, but also in a carpentry workshop when working with wood or plywood.

Simple model for gluing corners

To make such a clamp with your own hands, you will need four steel corners of the same size, a threaded stud, two wing nuts, a drill, and a welding machine.

Two corners are welded together at a right angle, getting an even square in cross section. The next step is to weld the threaded studs inserted into the drilled hole of the same diameter. Holes must also be drilled in the remaining corners. The ready clamp is easy to assemble. To do this, you just need to clamp the glued wooden parts with wing nuts.

If it is necessary to glue large planes, you can take steel corners of greater length and install additional studs also from the bottom of the clamp.

Homemade tape clamp

This type of clamp is often used to make picture or photograph frames. Such a clamp is a universal mobile mechanism with which you can glue the corners of frames of various sizes.

For the manufacture of such convenient fixture you will need 6 mm plywood, a wooden block, 10-15 mm thick plywood, a jigsaw, a screwdriver, a metal square, a simple pencil, a dense tape with a clip, bolts, washers, wing nuts.

The first step is to make a "table". To do this, we take a rectangular sheet of plywood and fasten two wooden bars on the screws on the bottom from two opposite sides. Next, you need to clearly measure and draw the diagonals along which cuts for the structure will be cut with a jigsaw.

The next step is to make four frame holders from thick plywood. First you need to cut 4 identical pieces of plywood rectangular shape, then using a metal triangle, draw identical right angles on one side and cut them out. You also need to make a slot for the bolt so that the clamp has mobility and can move left and right. To prevent the stretched tape from jumping off, you can cut a recess on the opposite side of the corner.

Clamp

This type of clamping mechanism is designed for work that does not require particularly strong and tight compression of parts, since it does not have a strong connecting effect. Such a clamp can temporarily and quickly fix the part, for example, when cutting. It works due to the eccentric located in the middle of one of the parts of the clamping device.

For manufacturing you will need wooden bars or thick plywood, metal plate, self-tapping screws, screws, bolts, drill, circular saw, sandpaper.

The first step is preparing wooden blocks. Their shape can be different, at the request of the master. It doesn't play a big role. A cut is made in the back, about 6-7 cm. A metal plate is inserted into the fixed part of the clamp with a preliminary drilled holes and bolted securely. On the moving part, the fasteners do not pass through the plate, but are located along the edges. The bar should move up and down.

Further work continues on the moving part. On the saw, a longitudinal cut is made, leaving a thin strip at the bottom. It will act as a clamp and should move. The cut is also made for the eccentric, which is screwed to the top of the part.

The eccentric is easy to do. With a compass on paper, draw a semicircle, the ends of which are connected by an angle. It turns out the form of a drop. Transfer the dimensions to thin plywood and cut with a saw. In order for this part to fulfill its role and put pressure on the moving part of the bar, we shift the center of the semicircle by 1 cm and drill a hole, attaching it to the upper bar with a screw. When turning the eccentric, the part is tightly fixed and quickly clamped.

Table clamp

Very easy to use and easy to perform desktop clamp. A wooden beam, a piece of plywood, bolts, a drill, a threaded stud and a metal stick for the lever are taken. Two bars are bolted onto a sheet of plywood, which are motionless on the table. Then the clamping device itself is installed.

A hole is drilled in one of the bars, into which a threaded pin is inserted, securely screwed into a smaller bar at a right angle. A lever is inserted into the free end for convenience. Very fast and easy, even a beginner can handle it.

Simple wood clip

This G-shaped design is designed to hold two planes when gluing. Having made several copies, you can fix all the corners. To work, you will need a wooden beam, plywood, a threaded stud, a nut, screws.

Having twisted three identical pieces of a wooden beam, we firmly fix it with the help of two rectangular pieces of plywood. Next, drill a hole for the stud. To make it move well, you can drive a nut tightly into a wooden beam, along which the stud will spin freely. The handle can be made at your discretion either wooden, or by inserting a simple lever from a metal stick.

Lamp installation

With the help of clips, you can rearrange the table lamp to a place convenient for reading: on desk, bed, nightstand or hanging shelf. The lamp on the clamp is convenient to use, therefore it is popular.

Quick clamps such as clamps can be used in all areas of life and production. Making them with your own hands is not difficult, you just need to allocate a little time and have a desire. Successful work!

Buying clamps is very expensive. Therefore, in order to avoid unnecessary expenses, it would be useful to know how to make a clamp with your own hands. Quite often, in the manufacture of furniture or wooden products, clamps are required in in large numbers. Especially if wooden crafts produced professionally. To make clamps on your own, you will need primitive improvised materials that everyone has available. In addition, the work process itself is not complicated and does not require professional skills, which will allow you to quickly create the necessary auxiliary tool.

Clamp scheme: a - parts, b - assembled, 1 - rectangular hole, 2 - pusher, 3 - body wall, 4 - ledge, 5 - hole in the body, 6 - clamping screw, 7 - movable jaw, 8 - lever, 9 - ledge, 10 - threaded holes, 11 - screws.

What is a clamp, and is there any point in making it yourself?

A clamp is an auxiliary tool that is used to fix the boards when they are connected (using glue, fasteners, etc.) or, if necessary, to compress them. Usually clamps are made of metal or wood. A clamp is also used to cut boards evenly, to make wiring for a hacksaw, to connect various parts and elements, etc. Wherein homemade clamps are in no way inferior to the purchased ones. To understand the principle of making a clamp with your own hands, you should understand its design.

Such clamps consist of 2 elements - a “body” (frame) and a fixing element (movable clamp). There are clamping jaws on the movable element and the frame, and for better fixation, the movable element is equipped with a lever. Lever clamps are also sometimes found, but they are rare due to their difficulty in manufacturing, as in industrial enterprises as well as at home.

The operation of the clamps is simple: parts (or material) that require processing are inserted into the body of the tool, then the working material is clamped with a moving element (clamping occurs with sponges), after which you can start processing or working with parts or material.

In most cases, the number of clamps required for a particular operation is not limited to 1 pc. For a tight fixation of the hacksaw, use 2 pcs, for fixing wooden planks- from 2 or more (depending on their length). In addition, if you want to connect parts, it is recommended to use a pair of clamps. Many people forget to take them off after work is done, which often leads to the loss of the tool. And primitive factory-made metal clips are not cheap, which makes it cost-effective to make such tools yourself. Below we will consider how to make carpentry clamps from wood and metal, and how an angle clamp is made by hand.

Making a wooden clamp

It is much easier to make a wooden clamp than all other types of such a tool. Such clips are very convenient when performing various carpentry work.

To make them you will need:

• pieces of boards (you can plywood);
• studs (which should be pre-threaded);
• nuts (for threaded studs);
• slats.

For the manufacture of the clamp, two studs 200 mm long with pre-threaded threads and 2 studs 120 mm long should be prepared. It is important that all 4 studs have the same diameter. Next, nuts are selected under the thread of the studs, two rails are prepared. Reiki should be prepared from hardwood. Oak is ideal, but beech, birch or ash slats are also suitable.

Then the slats need to be made the same in size. To do this, saw off all the excess and produce grinding. Then 2 holes are drilled in each rail. The holes must be at the same points on each rail. The diameter of the holes must match the diameter of the studs.

The next step is to stick plywood (as sponges) on the surface of the slats. When the plywood is glued, all the protruding parts are cut to the size of the battens, and the plywood sponges themselves are drilled through the holes in the battens.

Then long slats are inserted into the resulting holes. They will act as guides.

After the guides are installed, they are fixed with nuts to the rails. 2 nuts are screwed onto each guide.

Next, insert short studs. To make them immovable, the studs are riveted on one side. It is important that one hairpin is riveted with back side one rail, and the other - from the back of the other. Nuts are used as clamps. In order to make it more convenient to tighten them, lamb nuts are used. In this case, it is important to cut the threads on the fixing studs along their entire length.

This completes the manufacture of the wooden clamp.

How to make a screw metal clamp

To make such a clamp, you first need to prepare the materials. For the clamp body, you can use a sheet of steel about 1 cm thick or even and straight metal cuttings of the same thickness. The length of the workpiece depends on what working distance the clamp will have. For manufacturing, you will need long screws or bolts M8 or M10.

At the beginning of the manufacturing process, markings of the future tool body are applied to the workpiece material. Often the body of the instrument looks like the letter "C". In this case, the thickness of the workpiece can be different. It depends only on the required length of the working area. When the markup is applied, the part is cut out. To do this, at home use gas cutters, acetylene torches or a grinder. The grinder is used for workpieces of small thickness, it is problematic to use it when cutting out small curly elements.

When the workpiece is cut, it is polished with files, sandpaper. Grinding is an important process, if you do not grind the part, then there is a chance of cutting yourself on sharp edges when working with a tool.

Then, on one side, fasteners are made for the movable element. To do this, M8 or M10 nuts are welded to one of the sides of the clamp body. If there are no bolts or screws of sufficient length, hexagons or rebar of the desired length can be used. They should be threaded first. A flat flat part (on the working side) is welded to the end of the screw, which will act as sponges. A lever is welded on the opposite side (studs can be used as a lever), which should simplify the clamping process. This completes the manufacture of the clamp.

Another option is to make a clamp like a caliper. For this, a sliding frame made of steel strip is used. The end of the strip is flattened, and sponges are welded to it. Further, a movable element is made from the same strip, to which nuts are welded and a screw is screwed in for fixation.

It is more difficult to make such a clamp, but it has a longer stroke and, accordingly, a larger working area.

Angle clamp

In order to manufacture angle clamp, you need to accurately maintain the angle of 90 o. To do this, you need a square. Corners and steel strips can be used as materials.

To make such a clamp, you should install a square, to which the corners are applied so that the legs of the resulting rectangle are equal. Next, the corners are fixed on the square with improvised materials. They are applied metal strips. The strips should be fixed and then welded.

Nuts for moving elements are welded to the corners. It is advisable to use 2-3 nuts for this. Their task is to provide the best fixation. Long bolts should be used as fixing elements or metal rods with cut thread. At one end they should be welded on a flat plate as sponges, and for more convenient operation, a welded lever is used. This work is completed.

Angle clamp is the most difficult to manufacture, however, for some jobs it is simply irreplaceable.
